WASHINGTON (Reuters) - The latest draft of President George W. Bush's new Iraq strategy calls for an increase of more than 20,000 troops, with most going to Baghdad and 4,000 to Anbar province, a defense official said on Tuesday.

The plan -- due to be unveiled by Bush on Wednesday -- also calls for responsibility for security for all the country's provinces to be turned over to Iraqi forces by November, the official said, speaking on condition of anonymity.
